In this work, we report the synthesis, structural characterization of Group 4 mono and bis-hydroxides their derivatives catalytic properties in Ring Opening Polymerization (ROP) rac-Lactide. The hydroxides, multimetallic assemblies were characterized, using 1H NMR, 2D Elemental Analysis, Single crystal XRD. These complexes used as catalysts for ring opening polymerization All exhibit varied act...

Reactions of alkali metal hydroxides with neat diethyl zinc lead to the formation of oxo-centered clusters M2O(ZnEt2)n (M = Na, n = 3 or M = K, Rb, n = 4). These molecules crystallize in highly symmetric space groups, forming extended structures supported by weak M-H interactions. We discuss the mechanistic implications and relationship of these structures to known (oxo)organozincates.

Bentonite modified with ferrocyanides of Fe, Cu and CuK was tested for sorption of Cs137 and Sr-90 and proved to be highly selective for Cs; ferrocyanides of Cu and CuK are also good sorbents for Sr. Bentonite modified with hydroxides of Ti, Sn and Sb are good for Sr removal.
